Python - 显示 3D 点云 [英] Python - Display 3D Point Cloud

问题描述

我有一个包含 3D 点云的 .PLY 文件:我想绘制它并在 Python 中对其进行可视化..PLY 文件只包含顶点而不包含面.

I have a .PLY file that contains a 3D Point Cloud: I want to plot it and visualize it in Python. The .PLY file contains ONLY vertex and NOT faces.

你能告诉我一个简单的 Python 库来处理 3D 点云的绘制吗?

重要的是要指出我对绘制网格不感兴趣，而只是对点云感兴趣.

It is important to remark that I am not interested in plotting a Mesh, but just the Point Cloud.

推荐答案

对于任何想简单方法在 Python 中读取和显示 PLY 点云的人，我的回答是自己的问题报告我发现在我的情况下最好的解决方案.

For anybody wondering for an easy way to read and display PLY point clouds in Python I answer my own question reporting what I've found to be the best solution in my case.

打开cmd并输入:

pip install open3d

这将在您的机器上安装 Open3D，然后您只需执行以下示例脚本即可读取和显示您的 PLY 点云:

This will install Open3D on your machine and you will then be able to read and display your PLY point clouds just by executing the following sample script:

import numpy as np
from open3d import *    

def main():
    cloud = read_point_cloud("cloud.ply") # Read the point cloud
    draw_geometries([cloud]) # Visualize the point cloud     

if __name__ == "__main__":
    main()
